Warning to re-create index.dat after 20130705:

The format of dcmqrdb's binary index.dat file changed on 20130705 due to a
bug fix in the corresponding code. An index.dat file created before that date
will not work with dcmqrdb code compiled after that date but must be
re-created.
Minor fixes, e.g. added Doxygen markup.
Fixed issue with CP-246 files and private tags.

According to CP-246, elements with VR=UN and undefined length should be
interpreted as a sequence with implicit VR. This fix makes sure that the
code also works with private tags. It also corrects a wrong log message.
Thanks to Mathieu Malaterre <malat@debian.org> for the original report.
Slightly changed output of print() method.

Invalid codes are now printed if the "printInvalid" parameter is true. By
default, the text "invalid code" is printed in such cases. Before this
modification, invalid codes were never printed and the behavior of the
"printInvalid" parameter was different.
Added new print flag for showing invalid codes.

Added new print flag value that allows for showing also invalid codes.
This is especially useful for debugging purposes.
Added new option for printing invalid codes.

Added new command line option that allows for printing also invalid codes.
Create DcmFileFormat from DcmDataset w/o copying.

Added possibility to create DcmFileFormat from existing dataset and let
DcmFileFormat take ownership for that dataset instead of always performing a
deep copy.
Do not copy DcmDataset during C-GET receive.

C-GET functionality does not copy the dataset any more in the standard
storage handler.
Added missing references to closed DCMTK features.
Fixed typos.
